of course i have, read through what i said in the last posts
in summary
kjet is more responsive on the throttle
kjet is simpler and cheaper to setup
kjet is just as fuel efficient
kjet has been proven up to 200bhp, at which point your gonna want to turbo or throttle body the engine anyway
kjet is great out the box, you dont need chips to make it work properly
the only drawback i can see is as you said the fuel map is compromised, but in the real world this is a tiny difference.
anyway im not proving its better, im proving its not 'crap' as you have said, but in my opinion it is better.
look at the kjet 8v vs digifant 8v
